To all whom z't may concern.'

Be it known that I, HOWARD M. BARBER, a citizen of the UnitedStates, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Inking Mechanism for Bed-and-Cylinder Printing-Presses, of which the following is aspecificatiton.

The object of this present invention is to provide a novel inking mechanism for bed and cylinder printing presses in which the rollers are always driven in the same direction and in which a continuous even distribution of the ink on the form is ob' tained, the ink always being .worked in one Vdirection and the form rollers always being in contact with the vibrators during both the printing and return Strokes of the bed for insuring a thorough distribution of the ink on the form rollers.

In the accompanying drawings, Figure 1 represents in side elevation so much of a bed and cylinder printing press as will 1ve a' clear understanding of the invention. F ig.` 2 is a detail section through the inking mechanism. Fig. 3 is a detail section showing certainof the geared connections. Flg.

4 is a'n inverted sectiontaken in the plane of the line AwA'of Fig. 2, and Fig. 5 is a detail view showingv more clearly the means for vibrating the rolls 13, 14, and the inkl cylinder 6.

The sheet delivery mechanism and the mechanism for lreciprocating the form bed are not shown herein as they form no part of the present invention and `will not asslst in a clear understanding thereof.

The reciprocatingbed is denoted by 1, the form thereon by 2, the impression cylinder by 3, the fountain roller by 4, the ductor roller by 5, the ink cylinder by 6, the distributing and carrying rollers by 7, 8, 9, 10, 11, 12, the vibrators by 13, 14 and the form rollers by 15, 16, 17, 18.

Themain drive shaft is indicated at 19, which shaft drives the cam shaft 26 through the gears 20, 21, 22, 23, 24, 25. The cams for controlling the movements of the fountain roller 4 and the ductor roller 5, are denoted by 27, 28, respectively, and their shaft by 29, which shaft is driven from the cam shaft 26, through the gears 25, 30, 31, 32, 33, 34. The impression cylinder 3 is driven from the drive shaft 19, through the gears 20, 21, 35, 36. The ink cylinder 6 is driven from the impression cylinder gear 36, through the gears 38, 39, 40, 41, and the vibrators 13, 14, are driven from the ink cylinder gear 41, through the gears 42, 43 and 44, 45 respectively.

The form rollers l5, 16, 17, 18, are mount'- ed in bearings 46, 47, 48, 49 on rocking arms 50, 51, 52, 53 located at opposite ends of the roller shaft. The arms 50, 51, are loosely mounted on the shaft of the vibrator 13, and the arms 52, 53, are loosely mounted on the shaft of the vibrator 14, so that as these arms are raised and lowered by the mechanism to be immediately described, the form rollers will be at all times in contact with their respective vibrators. A cam 54 controls the raising and lowering of the form rollers 15, 16, 17, 18, as follows: A cross shaft 55 has fixed thereto an arm 56 having a stud or roller 57, engagedby the cani 54. At each side of the machine, this shaft 55 has fixed thereto an arm 58. Three angle levers 59, 60, 61, have their correspondlng arms connected by a rod 62, for causing these arms to be rocked in unison. The other corresponding arms of these angle levers are connected to the free ends of the arms 51, 52, 53, by rods 63, 64, 65, the rod 63 being connected to the arm 50, the

rod 65 to the arm 53 and the rod 64 to both the arms 51, 52. These angle levers aie rocked by connecting one of the levers to the arm 58, by a rod 66. The cam 54 on the shaft 26 is so timed that the form rollers will be lowered into contact with the form 2, during the forward printing stroke of the bed and will be raised to clear the form during the return stroke.

The rolls 13, 14, and t-he ink cylinder 6 may be vibrated by any desired means such as that shown in the accompanying draw-l ings in which the shaft 6* of the ink cylinder 6 is reciprocated longitudinally by the worm 67 and worm wheel 68. The shaft 13*, 14*, are reciprocated longitudinally b the rocking levers 69, 70, from the ink cyl-7 inder shaft 6*. It will be seen that these form rollers are 4always driven in one direction by their contact with the vibrators, thus accomplishing the following results:

first, the working of the ink in one direc-u tion; second, a continuous even distribution, and third, the ability of the machine to be successfully run at a higher rate of speed lio4 because of the non-reversing movement of said rollers.

It is evident that various changes might be resorted to in the construction, form and arrangement of. the several parts for accomplishing the results herein stated; hence I do not wish to limit myself to the conf.
